Notes & Tips :-
1.Check LLC resistor, make sure it's 931 Ohm (Vdroop around 0.026v). Do not use "Gamer Load" in NVVDD 0508. If Vdroop higher than 0.07v, LLC mod might be needed
2.Check Thermal Shutdown (Normal -160c CB & -75c CBB) & Power Limit (Below 30% at Load) switch at back of card, make sure it's on default "Disable" position (Opposite to "On") Retail V2 might be different.
3.Make sure the black "OC Button" above HDMI plug-in is ignited (pushed in) to further release the power limit.
4.Suggest using single PSU with OCP disabled. Single rail is NOT necessary. Power consumption for 780ti 1800MHz or above is very high.
5.If dual PSU is used, make sure the PSU for yr card is on b4 you boot up mobo. Suggest using a starter for card PSU separately from MB PSU with NO "relay" connected to it
6.The best temp is below -130c for benching, -160c not much help for higher clock
7.Max voltage set is 1.625v or below. Best Vgpu I found is around 1.606v for 19xx clock FS/FSE. Vmem +160mv to 240mv to reach 2100 memory. 3DM11 needs higher voltage. Most of the V20 can do 1900MHz FS/FSE and 1800MHz 3DM11/Vantage
8.When testing, keep reading of each voltage measure. Once OC fail, you will know which part has a sudden weird voltage drop. Please find measure holes behind the card
9.Make sure your GPU pot is well attached. When artifacts appear at high clock, mostly due to bad insulation. If no artifacts but driver fault, not enough Vgpu
10.Easy to see broken thermal paste lower than -130c. When you hear cracking sound out of yr gpu pot, stop & remount. No point to keep pushing
11.Critical to keep well insulated pot for high gpu clock benching
12.Do GPUz rendering test 1st b4 real benching. A good card at 1800MHz needs only 1.45v for render test, but + 0.036v for actual benching
13.1900MHz needs much higher voltage and lower tem. You need to find the sweet pot !!
14. No mod is needed, except when dual psu is used
15. Use D-Sub for DVI cable
